Product Details

The Gates Accessory Belt Drive Kit line is built to simplify full-system service on the serpentine drive. Instead of replacing only the belt, this kit addresses the belt and tensioner together, which helps maintain proper belt tracking and tension across the accessory drive. For vehicles such as the Buick Century, Chevrolet Impala, Chevrolet Monte Carlo, and Pontiac Grand Prix, the Gates 90K-38353 provides the core components needed for a complete front-end belt drive refresh.

This part cross-references Continental K49395 for the same application.

What It Helps Fix

• Squealing or chirping from a worn serpentine belt
• Loss of belt tension from a weak tensioner
• Uneven belt wear caused by aging drive components
• Accessory drive noise from worn front-end belt hardware
• Repeat repairs when the belt is replaced without the tensioner

Installation Notes

Verify belt routing and confirm the belt number K060703 and tensioner assembly 38353 before installation. Review the vehicle-specific notes for each application, including the 1998 Oldsmobile Silhouette and 1998 Pontiac Trans Sport listings that require a 140A alternator. Follow the included installation instructions and tech tips for accurate service on the serpentine drive system.
